MACl-HNE FOR INSERTING METALLIC FASTENINGS.

SPECIFICATION forming part of Letters Patent No. 669,024., dated February 26, 1901.

Original application filed October 26, 1899, Serial No. 734,828. Divided and this application filed January 23, 1901. Serial No.4 h375. (No model.)

To all whom it may concern:

Be it known that I, LOUIS A. CASGRAIN, a citizen of the United States, residing at Winchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Machines for Inserting Metallic Fastenings, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to a machine for forming and inserting fastenings having shanks or bodies and heads provided with depending points, constituting hook shaped heads.

The present application is a division from another application, Serial No. 734,828, filed by me October 26, 1899. In the machine described and claimed in said application, Serial No. 734,828, the length of the shanks of the fastenings was varied automatically according to variations in thickness of the stock; but in the machine of this application the character or length of the shank of the fastening is determined by the workman through manually-operated devices.

Figure 1 represents in side elevation, with the driving-pulley removed, a portion of the machine represented in application Serial No. 734,828, filed October 26, 1899, with mypresent improvements added. Fig. 1 is a detail showing the means for moving the regulator. Fig. 2, on a smaller scale, represents the lower end of the column, showing the treadles. Fig. 3 is a plan view of the parts shown in Fig. 2. Fig. 4 is a detail in plan view of the wirefeeding means and actuating devices therefor. Fig. 5 is a sectional detail in the line 00, Fig. 4, of the wire-feeding means. Fig. 6 shows the two manually-controlled levers for actuating the regulator, said levers being substituted for other levers fully shown and described in said application; and Fig. 7 represents, on an enlarged scale, a fastening such as will be made on the machine described.

Referring to the drawings, the column A, standing on the floor and sustaining the head A in which is mounted the main shaft C, the stud D, the starting lever or device 0 having as its fulcrum the rock-shaft C and provided at one end with a stud C and having the extremity of its connected arm C beveled, said starting-lever being moved in one direction to start the main shaft of the machine and moved in the opposite direction by a spring C the Wire-feeding means, (represented as wheels 0 0 deriving their movement from spring-pressed pa wls 0 0 mounted on a toothed pawl-carrier e actuated by a slide-bar 6, connected with a lever E, said pawls engaging a ratchet-toothed wheel a, fast on the shaft 0 carrying the feed-wheel c, and the regulator 6 having shields e and e for controlling the time at which said pawls in the stroke of the pawl-carrier, which is uniform, shall engage the ratchet-wheel, and thereby insure a definite amount of movement of the Wire to be formed into a fastening, are common to the machine shown in said application. In said application, however, the extent of feeding movement imparted to the wire, and consequently the length of the fastenings, is controlled automatically by variations in the thickness of the stock, while in the machine of my present application I have provided novel devices wherethrough the length of the fastenings is determined by manually-operated devices under the control of the workman.

In the machine herein shown the column A has at its lower or floor end a pivot D which sustains two treadles D D and each treadle has a suitable arm or projection with which is connected one of two rods D D. The rod D is extended upwardly and has clamped upon it a block D having a stud which enters a hole in one arm 53 of a lever 0 having an upwardly-projecting arm 61 and a depending arm 52. The rod D is provided with a like block having a stud which enters a hole in an arm 51 of a lever o, having an upwardly-extending arm 60 and a depending arm 50. These two levers 0' and 0 have their hubs bored and are both pivoted on the stud D.

Herein the stub 0, carried by the startinglever, is longer than in the machine of said application, and said stud is arranged to be acted upon by either of the arms 60 61 of the levers o 0 and either of said levers may be turned by the workman through one of the treadles D or D to start the main shaft vC of the machine through means fully described in said application.

Herein the regulator 6 instead of being moved by a single .rod, as provided for in said application, is moved by either of two rods, as 54 55. The rod 54 is moved by the arm 52 of the lever 0 while the rod 55 may be moved by the arm of the lever 0'. rods has a stop, as 56 or 57, and by adjusting these stops more or less of the movement of the levers 0 or 0 may be made effective in moving the rod connected with it, and consequently the regulator e carrying the shields e and e As fully explained in said application, changing the position of the shields with relation to the ratchet-wheel varies the time of'engagement of the pawls 0 and e in their forward stroke with said ratchetwheel, and thereby regulates the operation of the wire-feeding mechanism and causes the production of fastenings differing in length.

The stops 56 and 57 are preferably held frictionally in position upon the rods 54 and by suitable set-screws, as 58, which bear against suitable washers 59, contacting with the rod.

It will now be seen that in the machine embodying my present invention the workman will by simply depressing one of the treadles both start the machine and operate the mechanism which controls the length of fastening to be produced by the machine. It will also be understood that by the single operation of depressing one treadle the workman both starts the machine and causes the production of a fasteningof a predetermined length, while by the single operation of depressing the other treadle the workman both starts the machine and causes the production of a fastening of fully described in said application, so thatthe shanks of the fastenings and the points depending from their heads may stand crosswise of the sole, and at this time the workman standing in front of the machine will present the shoe to the usual nose I), so as to receive from it the fastenings inv the direction stated and will start the machine by putting his foot on one or the other of the treadles Each of these D D, according to the length of the fastening desired. Other manufacturers, however, desire that the shanks and the points depending from the heads shall stand in a line substantially parallel with the edge of the sole, and at such time the workman for convenience of handling the shoe may prefer to stand at the right-hand side of the machine, and to permit this the treadles D and D have been provided with supplemental footpieces \Vith the levers having the extra footpieces 19 19 the workman may operate the machine with equal convenience whether standing in front of the machine or at the right-hand side thereof.

When the lever 0 is actuated by its treadle, the rod 55 moves the regulator to put its shield in such. position about the toothed surface of the ratchet wheel c of the wire-feeding mechanism that the spring pressed pawls 0 and 0 when the pawl-carrier is moved, as stated, will meet the teeth of said ratchetwheel and move the wire-feeding mechanism for a distance to make, for instance, the longest fastening, and such movement of the rod 55 in the direction of the arrow near it, Fig. 1, will move the stop 56 of the rod 54 toward the end of the arm 52 of the lever 0 So long, as the operator retains his foot on the treadle D controlling the movement of the lever 0, the longest fastenings will be made and driven; but on arriving at the shank, where a shorter fastening should be inserted, the operator will remove his foot from the treadle D and put it on the treadle D causing the arm 52 of the lever 0 to be moved in the direction of the arrow y near it in Figs. 1 and 1, it pushing in front of it the stop 56, with which it is in contact. The rod 54 will thus be moved to put the shields in such position with relation to the ratchet-teeth of the wire-feeding mechanism that when the pawls again go forward they will be prevented by the shields from engaging said ratchet-teeth until a later pointin their stroke, so thata shorter fastening will he produced. During this operation the rod 55 will be moved opposite the arrow next to it, thus moving the stop 57 toward the arm 50 in readiness to be acted upon when a longer fastening is again required.

I provide the regulator with a friction device f which acts against a fixed part of the machine, and by turning a screw f (see Fig. 5) I may cause said device to exert any desired amount of friction, so that the regulator will not be moved accidentally and can be moved only when actuated positively by the rods 54 or 55.

In order to control positively the-positions of the shields in making the different lengths of fastenings, I have provided means whereby the movements of both treadles in each direction are limited. The lever D has been provided with a suitable pin or projection 1" and the lever D with a projection 0", said projections each entering suitable notches 1' in a depending guide or bar W, said notches being of lengths corresponding to the movements desired for the treadles. The under sides of the notches limit or determine the extent of downward movement of each treadle under the action of the foot of the work-' man and the upper ends of said notches determine the extent of upward movement of each treadle under the action of a spring D common to said application. I have so arranged the pins 9* and r and the notches r that the footpiece of each treadle, when it is depressed to its low position, is at a considerable distance from the floor, so that a full movement of the treadle is assured even in case there should be some obstruction below the footpiece.

I have shown these mechanisms as being adapted to cause the presentation to the machine of different lengths of fastenings, and I believe I am the first to use separate actuating mechanisms arranged for the starting and stopping of the machine and also for causing the insertion of fastenings of different arate actuating mechanisms each adapted to start and stop the machine and also to control the presentation of a fastening to be inserted by the machine in the stock. I also believe that I am the first to embodyin a machine for inserting metallic fastenings formed from continuous wir'e an actuating mechanism adapted both for starting and stopping the machine and for controlling the action of the wire-feeding mechanism to determine the length of the fastening to be formed from said wire.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
